Abstract:

A theoretical research program was conducted to investigate the feasibility of improving the aerodynamic lift and drag characteristics of a highly loaded lifting surface by creating a favorable wing vortex interaction with concentrated line vortices located adjacent to the wing. Beneficial wing vortex interactions are found to be responsible for improved aerodynamic performance of high lift devices such as strakes, canards, and leading edge snags. A simplified analytic model has been developed.
